Do I need a transit visa in Bangkok if I have a 6-hour layover and need to check my baggage again?

When you have a 6-hour layover in Bangkok and need to check your baggage again, whether you need a transit visa depends on several factors: the ticket type (if it's booked through to your final destination and whether you need to collect your bags), your nationality (visas exempt countries may not need one), and whether you'll be passing through immigration. It's advisable to check directly with the airline or inquire at the airport during check-in for the most accurate information.
